Justin Tucker is the only confirmed Ravens player who will be available today, from 12:30 p.m. to 3:30 p.m., when fans can pay $50 to hitch a 10-15 minute ride in downtown Baltimore.

An Uber spokeswoman blamed the revisions on "last minute schedule changes and lots of little things."

Uber, which has offered hirable sedans in Baltimore since January, says fans can still use its app to summon a player on-demand for a 10- to 15-minute ride. Participants can take up to three friends along and all rides will end at Fells Point Square.

On Monday, Tucker, the Ravens' kicker, tweeted about it: “Pumped to be on-demand in the Uber app tomorrow. Get the app and come roll with me in Baltimore!”

Participants will also receive a $50 gift card to Mother's Federal Hill Grille, but the VIP experience at Under Armour Brand House and the Natty Boh gift basket are no longer part of the deal. Instead, riders will receive various Baltimore swag, including T-shirts.
